we have about six oracle instances running on a box and I need to know if we can add one more instance. When I do a top I get the below output:

I see there is very little physical memory free but arnd 5gig of swap free. I wana know can I add one more instance which can use swap memory:


top - 12:05:43 up 17 days, 12:37, 1 user, load average: 2.88, 2.62, 2.31
Tasks: 423 total, 4 running, 417 sleeping, 0 stopped, 2 zombie
Cpu(s): 15.9% us, 1.1% sy, 0.0% ni, 64.8% id, 17.6% wa, 0.0% hi, 0.6% si
Mem: 37027764k total, 36905684k used, 122080k free, 219532k buffers
Swap: 56623096k total, 240k used, 56622856k free, 8556596k cached

if you need any further details. please let me know.

thanks! Razz
